Sure - I remember Jambu introduced his teacher who attended our wedding in 1969 -
Tiger Thathachari - his Maths teacher - he was கணக்கு புலி - otherwise be was சாது like a பசு! We always remember such great teachers But his son turned out to be ஒதவாகரை ! புலிக்கு பிறந்த பூனை ! That could be his lineage pride!
May be ordinary Jambulingams can not afford a Tiger and have to be content with a Poonai for learning maths.
And Jambu maamis in the home can not manage a tiger and so will be happy to have a poonai for their vambu whether in kitchen or in the forum.LOL.
